Log in server busy?

I just bought cataclysm from the battle.net. Then I downloaded a small patch and now i can no longer logg into wow because the login server is busy. Its been like this for 2 hours now. I can log on to my friends account fine but she does have an authencator on her account but I do on my account. Anyone know what I can try?

I am experiencing the same problem. I have no authenticator, and haven't bought or begun installing Cataclysm, so it seems to be a general problem. It's probably being altered with people having to login to get their download going.
